Implements the 6 behavioral archetypes from D-175 (Burnelli-Sheldon):
Producer — 1.15× production scale, neutral price signal
Distributor — 0.9× production, −3% price discount to move volume
Specialist — 1.0× production, +10% price premium for expertise
Monopolist — 0.8× production, withholds 25% of output, +20% premium
Cooperative — 1.0× production, −5% community discount
Intermediary — 0.7× production, relies on traded goods
Archetype loading:
- Reads from corporations.behavioral_archetype (currently NULL for all corps)
- Falls back to heuristic inference from specialization text (freight → Distributor,
extraction → Producer, luxury goods → Specialist, etc.)
- 48 corps loaded on current DB, all inferred (DB column to be populated when
wiki corp frontmatter is extended with the behavioral_archetype field)
Applied in model.rs step():
- Per-corp effective_capacity = BASELINE_CAPACITY × production_scale
- Monopolist supply_withheld fraction reduces net output to stockpile
- Price premium: small ALPHA-scaled nudge to node price for primary commodity
All D-179 stability checks still pass with archetypes active.
